Answer:

x = -2

Step-by-step explanation:

1/3(x - 10) = - 4

1/3x - 10/3 = - 4

1/3x = -4 + 10/3

1/3x = -2/3

x = -2/3 · 3

x = -2

Answer:

x=-2

Step-by-step explanation:

First use distributive property

1/3*x and 1/3*-10

=1/3x-10/3=-4

Then add 10/3 on both sides so x can be by itself

=1/3x=-4+10/3

Then add -4 and 10/3

=1/3x=-2/3

Then multiply each side by the reciprocal of 1/3 which is 3/1

x=-2

What are the steps for this problem? -10-8n=n-(8n+8)

Elden [556K]

Answer:

$n = - 2$

Step-by-step explanation:

$- 10 - 8n = n - (8n + 8)$

First, you should distribute the -1 on the right.

$- 10 - 8n = n - 8n - 8$

Next, add 8n to both sides. This should cancel out the 8n.

$- 10 = n - 8$

Now, add 8 to both sides. This will get n by itself.

$- 2 = n$

Your answer is n = -2.

Factor completely. x2 + 5x + 6 A. (x - 3)(x + 3) B. (x - 1)(x + 6) C. (x + 3)(x + 2) D. (x + 5)(x + 1)

zhuklara [117]

being $x^{2} +5x+6$ the answer is (x-3)(x-2)

begin $x^{2} -5x+6$ the answer is (x+3)(x+2)

1. $x^{2} +5x+6$

second grade formala is used

$x= \frac{-b±\sqrt{b^{2} } -4ac}{2a}\\ x=\frac{-5±\sqrt{5^{2} } -4.1.6}{2} \\ x= \frac{-5±1}{2} \\ x_{1} =-3 \\ x_{2} =-2$
